Netflix's Stranger Things 2 — Final Trailer

Halloween is a joyous time for tricks, treats, and spooky things. Well, here's something that has all of that in spades.

Check out the final trailer "Stranger Things 2," the second installment of Netflix's hit science-fiction horror series, which returns later this month.

Created by Matt and Ross Duffer, aka the Duffer Brothers, the nine-episode thriller takes place a year after the events of the first season. The calendar now reads 1984, and the bike-riding gang from Hawkins, Indiana has begun a new school year.

Though still reeling from their traumatic confrontation with the "Demogorgon" monster, Mike (Finn Wolfhard), Dustin (Gaten Matarazzo), Lucas (Caleb McLaughlin), Nancy (Natalia Dyer), Jonathan (Charlie Heaton) and Steve (Joe Keery) are slowly getting back to some form of normalcy. While Joyce (Winona Ryder) and Hopper (David Harbour) are still unable to shake off their apprehensive feelings -- nor should they.

Since returning home from the "Upside Down," Will (Noah Schnapp) appears to be suffering from PTSD. He is afflicted by painful visions of some kind of impending doom. And whatever it is, it might be "spreading."

But the big question is where's Eleven (Millie Bobby Brown)? Well, she's back, but for how long?

The cast also now includes Sean Astin as a Radio Shack manager who went to school with Joyce and Hopper; Sadie Sink as a new kid student and Paul Reiser as a new shady government official.

The majority of the new season is directed by The Duffer Brothers with several episodes helmed by Shawn Levy (Night at the Museum), Andrew Stanton (Finding Nemo, Finding Dory), and Rebecca Thomas (Electrick Children).

"Stranger Things: Season 2" will be released on Friday, October 27th only on Netflix.
